Give back 'blue' for hair

Only human being has hair. All other animals have only feathers, though those hairs grow on their heads. Therefore, since ancient times, human beings have been able to beautify their hair. But hair is not eternal. It falls, shedding one strand at a time or shedding a large chunk. And that is one of the "buried pain" of many gentlemen today.

Hair reflects the state of people and their environment

First of all, we know that the visible part of the hair is the hair, a 'dead organ' according to the biological definition. But this is a place that provides a lot of valuable data for the sciences, especially archeology when determining the race and gender of the mummies. Meanwhile, the environmental sciences will analyze many components contained in the hair to find out what toxins exist where the person is living, including alcohol, nicotine and substances. addiction that the person uses.

On the other hand, hair is also very sensitive when we fall into a state of fatigue, exhaustion or a strong psychological shock. At that time, there will appear more plaque in the hair roots due to the phenomenon of seborrhea. Interestingly, hair fibers can also become a measure of people's heart health status. According to Harvard University Professor JoAnn Manson, men with hair loss at the top of the head are 34% more likely to develop cardiovascular diseases than those who only have hair loss on either side. positive.

Stay calm when you have hair loss

Hair loss occurs in about 20% of men between the ages of 25 - 35, and after 50 years of age, more than 50% of men suffer from hair loss. This is a problem that most men are interested in. Once you have unfortunately fallen into this spiral, gentlemen may stumble, fear, feel that you are 'old' in front of people, relatives and especially when facing women. This is considered a phenomenon of profound impact on the 'appearance' of men in terms of sociology. Since then, it has become a spearhead study of hair experts, with the aim of increasingly perfecting hair care products, drugs and hair dyeing methods and ultimately finding ways to The most effective treatment for baldness.

According to professional data, 90% of baldness cases originate from a double cause: inherited and from hormonal effects. Every hair that grows up is 'underground' carrying a genetic code from your parents, when your parents have hair loss or baldness, then the child will more or less suffer. In addition, when the subject itself is male hormonal dysfunction, when testosterone is too rapidly "transformed" into dihydrotestosterone, it will harm the hair, causing the hair growth time to be shortened. and the hairline will soon be destroyed. So the hair will fall out soon. Moreover, according to experts on skin and hair-hair diseases in Sabouraud center in Paris (France), hair can be lost due to psychological causes such as stress, due to heavy smoking, due to the effects of drugs Used in chemotherapy, when taking antidepressants, anticoagulants . And it is impossible not to mention the lack of diet in people with poor diets: vitamin deficiency, zinc and iron deficiency. From various causes, our hair will be 'devastated' and become ' more fragile' .

A reference number: if you lose about 150 hairs every day, watch out. This is pathological hair loss and worse, you may be getting bald! Of course, no one has enough time and effort to count every strand of hair every day, but if you feel and estimate that your hair suddenly loses about 3 times more than normal, be more careful. .

In the future, when 'baldness' is only a memory .

In France alone, there are 10 million men with baldness. To keep abreast of the latest achievements of the 21st century science and technology industries, the key biotechnology industries such as cell clones and stem cells are actively entering. At the University of British Columbia (Canada), Professor Kevin McElwee took the hair cells and then 'photocopyed' them into 'copies', then nourished them in the lab and finally inoculated them again. into the scalp layer of the patient. After a while, these "hair sprout" will develop into a new layer of hair.

The first tests by this method were conducted by the British company Intercytex in 2005 on 7 volunteers, with the result that 5 people were satisfied. In June, they will conduct other clinical trials to confirm the final result. However, a major limitation is that it is difficult to find the required number of hair pins!

Understanding this situation, in October last year, Swiss experts tested the production of 'finished hair roots ' from their source of stem cells. These 'hair products' will be able to grow in accordance with the growth cycle of the hair's life cycle to produce a 'real and perfect hair'. This must be a breakthrough biological revolution to help the hairs that fall out can grow again and again.

However, while waiting for new achievements to be widely applied, gentlemen are still temporarily satisfied with the method of hair transplantation. Although a bit classic, there are over 60% of men who have regained their confidence after seeing their hair still… green!

Beauty for hair

(Photo: hisandher) Beauty, that is, to talk about aesthetics, the 'maintenance or restoration of beauty'. It was indeed complicated when there were people who owned a completely 'green' hair but were not satisfied. They want to have a 'gecko' hair - when it's red, when it's yellow, when they're bright! And science is always following the will of people or 'changing hair' .

From time to time, we have known many methods of coloring hair. It's a lot, but there is a 'top' product of the year 2006 in the West that has received a lot of attention from the public: it's a 'hair color', also known as a color, generation. Latest. This type of machine will help customers to watch and compare carefully the color scheme to choose for themselves a hair color that best suits.

The silver hair dye has many methods. But recently, scientists have made an important discovery when it comes to understanding the 'dead' between melanoma and an enzyme called TRP2 . This enzyme has a major function in producing melanin, but when it is lost, the melanocytes are no longer available. Since then, scientists have embarked on a study of 'hair dyeing' by biological methods. They are testing how to create 'fake' molecules . These molecules will " pack " the TRP2 enzyme to function, to "fool" the melanocytes, making them not self-fatal because they think the TRP2 enzyme is still there. But it will take a few years for us to see the results. The hair expert promised so!

Why is 'blonde'?

Men like blondes. At least Western men. It happened in the time when humans lived in caves. According to Japanese experts, from a mutation of the gene, the first blonde girl was born 11,000 years ago in Europe, at the end of the ice age. At that time, women could not go out hunting and gathering because of the cold weather, they were completely dependent on men for food. But the proportion of men who have been "lost" too much after the hunting trips back, leads to a situation where the number of strong men surviving is quite small.

In the face of this "positive and negative" situation, nature was so harsh that once generous, it helped men of that time get an opportunity to make easier choices when they had to be "ambiguous" in a world. Only "brown hair": everyone is the same! So there was a mutation in the MC1R gene, which helped to create some particularly prominent subjects that caught the attention of men, who were 'blonde ladies'. According to Canadian anthropologist Peter Frost , the first "blond fairies" immediately caught the eye of the opposite sex. As a result, a small number of the few remaining men have been highly attracted and have 'rushed' into 'blond hair' to . maintain the race. And blonde hair has existed to this day.

According to Harvard University Professor JoAnn Manson, men with hair loss at the top of the head are 34% more likely to develop cardiovascular diseases than those who only have hair loss on either side. positive.

Hair helps bring the balance of justice?

On average, hair grows about 1cm each month. Therefore, a 6cm long hair will convey to investigators the "true stories" that its owner has experienced in half a year. Finding a hair may not be difficult, but if you want to get an intact strand of hair at the root of the case in the case of death victims is sometimes a problem.

In this case, experts have come up with an alternative: they will analyze a type of DNA called ADNmt (mitochondrial) in the mitochondria of normal hairs. But because this ADNmt provides only a part of the entire genetic code of the object because it is only transmitted from the mother, so in the opinion of molecular biologist Hélène Pfitzinger and also a forensic expert , 'ADNmt does not help us find the exact culprit, but at least it allows us to remove an object from the list of suspects'.

And there is one thing worth noting: we cannot scratch our heads to hide all traces, because other hair samples such as armpit hair or pubic hair completely provide the same information as the data. Data collected from within a hair. Hair, therefore, when defined as the most 'legal' way, is just 'hair growing on the head' !
